Building a kick-ass home theatre requires lots of money and lots of space for speakers, amps, and other equipment. But THX wants to replace all of that with their new Steerable Line Array speaker system that can discreetly hide under your massive TV.

Sony's 4K projector was first announced last year, but they have the thing on display at CES this year. After getting to zone out in a pitch black room where the projector blasted the new Spider Man trailer at full resolution on a 182-inch screen, I'm sold on the idea.

I'm sure there are 3.5 people out there who will put Sony's portable Blu-ray player to great use. It has a 9-inch screen, 4.5 hours of battery life, and 1080p output via HDMI. But for the rest of us, The Sony SX910 is an extremely niche-y, borderline unnecessary piece of tech.

Unless you're a home theater idiot-savant, you probably forget what HDMI port your Xbox or Blu-ray player is connected to, requiring you to randomly cycle through inputs. A task that's now a lot easier with InstaPrevue's live video thumbnail previews.

For the most part, itty-bitty satellite speakers are just all right—a compromise made for convenience. The new Boston Acoustics SoundWare S system looks like it might actually be able to blow up a room with sound.
